Problem: SAS cabling not valid

If a SAS connection is not valid, use this information to verify the accuracy of the system cabling.

Procedure

Verify that the SAS cabling is installed correctly by checking that all SAS connections meet the following requirements.

If a connection between the control enclosure and any host in the system is not valid, check that the SAS cabling between the control enclosures and the hosts conforms to the following SAS connectivity rules.
  • The cables that are connected to port 1 on each node canister in a control enclosure must attach to a redundant port pair on a host.
  • The cables that are connected to port 2 on each node canister in a control enclosure must attach to a redundant port pair on a host.
  • A connected port on the node canister must connect to a single port on a host. Cables that split the connector out into separate physical connections are not supported.
